Restore Peak Performance to Your GM Vehicle
Is your 2008-2009 Savana 1500 van running rough, stalling, or showing a persistent Check Engine Light? These are classic signs of a failing Powertrain Control Module (PCM), the central computer responsible for managing your engine’s performance, fuel economy, and emissions. A faulty PCM can lead to a cascade of frustrating issues, but the solution is straightforward. This replacement PCM, part number 12597125, is the definitive fix to get your vehicle back on the road and running like new.
This isn’t just a generic part off a shelf. We provide a fully programmed, plug-and-play solution tailored specifically to your vehicle. Upon purchase, you simply provide us with your vehicle’s VIN. Our technicians then flash the module with the latest, most stable GM-approved software for your exact make, model, and engine configuration. This critical step ensures seamless communication between the new PCM and all other vehicle systems, eliminating the need for an expensive trip to the dealership for programming.
From the Diagnostic Bay
We had a 2008 Chevy Silverado with the 4.3L V6 come in with an intermittent no-start and random stalling. The owner had already replaced the fuel pump and crank sensor based on some forum advice, with no luck. After connecting our scanner, we saw erratic data from multiple sensors and communication loss codes. Instead of chasing ghosts, we went straight to the source: the PCM. A quick swap with one of our pre-programmed units, like this 12597125, and the truck fired right up and ran perfectly. It’s a great reminder that sometimes the ‘brain’ is the problem, not the ‘body’.
Common Symptoms of a Failing PCM
- ✔ Check Engine Light is illuminated, often with communication-related (U-codes) or performance codes.
- ✔ Your vehicle fails to start or starts intermittently.
- ✔ Noticeable decrease in fuel economy.
- ✔ Rough idling, stalling, or hesitation during acceleration.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ The engine misfires or runs poorly, even after replacing spark plugs and coils.
- ✔ Inaccurate or non-functioning dashboard gauges.

Frequently Asked Questions
Do I need to send you my old computer?
No, there is no core charge or need to send your old module back to us. This is an outright purchase, simplifying the process for you.
What information do you need to program the PCM?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN). You can provide this during checkout or by sending us a message after your purchase. The VIN allows us to load the exact GM-specified software for your vehicle.
Is this PCM difficult to install?
For most DIY mechanics, installation is straightforward. It typically involves disconnecting the battery, unplugging the electrical connectors from the old PCM, unbolting it, and then reversing the process with the new unit. Some vehicles may require a security relearn procedure afterwards, which takes about 30 minutes and does not require a scan tool.
Will this fix my specific problem?
While this 2008-2009 Savana 1500 PCM resolves a vast majority of the symptoms listed above, proper vehicle diagnosis is always recommended. This part will fix issues directly caused by a faulty computer, but it will not fix underlying mechanical or wiring problems.
How fast will I receive my programmed computer?
Once we receive your VIN, programming is typically completed within one business day. We then ship the unit out promptly so you can get your vehicle repaired as quickly as possible.
